Title: Control method for optical multi-wavelength transmission equipment
Inventor: KAWAGUCHI AKIHISA
IPC: H04B17/00
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a control method for optical multi-wavelength transmission equipment for providing stable wavelength multiplexed light transmission by switching the control system of an optical amplifying part corresponding to the state of inputting the optical signals of respective wavelengths. SOLUTION: Concerning this control method, at the time of activating equipment, the initial setting of wavelength to be used or number of wavelengths to be used is performed, the quantity of optical attenuation concerning each wavelength is set to a maximum value S2, and an optical amplifier unit is set into ALC S4. When an optical signal corresponding to the wavelength to be used is inputted S5, an ordinary operating state is provided by controlling the quantity of optical attenuation corresponding to the wavelength of the input light S8 so that the optical signal level of respective wavelengths measured by a spectrum measuring unit can be almost fixed and the level of input light to the optical amplifier unit can correspond to the number of wavelengths to be used.  When the number of input wavelengths is changed, the optical amplifier is set into AGC and after each input light level is regulated corresponding to the number of wavelengths to be used again, the ordinary operating state is provided again by switching to ALC.

IPC: B41J2/345
Filed: 1983-12-24
Abstract: PURPOSE:To enhance printing quality, by setting the width of a heating part for preheating to be larger than that of a heating part for printing. CONSTITUTION:The width (b) of the heating part 8 for preheating is set to be larger than the width (a) of the heating part 7 for printing. The temperature of an insulating substrate 6 and the temperature of a thermal recording paper or an ink ribbon are previously raised by passing an electric current to the heating part 8, and thereafter printing is conducted by passing an electric current to the heating part 7. In this case, since the width (b) of the heating part 8 is larger than the width (a) of the heating part 7, end parts of dots to be printed are also sufficiently preheated, so that end parts of printed dots are not blurred, and high printing quality can be obtained.

Title: Method and device for measuring concentration of carbonate in slurry
Inventor: YOSHIKAWA HIROBUMI
IPC: G01N27/416
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for accurately measuring the concentration of CaCO3 in a slurry in a short time even if the concentration of CaCO3 in the slurry fluctuates abruptly. SOLUTION: In this measuring method, the flow of a slurry flowing in a measuring cell 8 is varied depending on the amount of fluctuation per unit time of the detected value of the concentration of dissolved CO2 in a slurry as measured by a dissolved CO2 meter 9. Preferably, when the amount of fluctuation per unit time of the value detected by the dissolved CO2 meter 9 is equal to or greater than a certain value, the flow of the slurry flowing in the cell is increased for a certain time and then returned to its initial value.

Title: Signal processing method
Inventor: KUDO YASUSHI
IPC: G10L13/00
Filed: 1993-10-07
Abstract: PURPOSE:To emphasize a spectral peak by analog signals and to compress a frequency band by dividing signals whose feature quantity is the spectral peak to the plural frequency bands, limiting amplitude for the respective frequency bands and extracting frequency components. CONSTITUTION:200-3400Hz are divided into seven frequency bands by band-pass filters 3A-3G and input speech signals are shaped into rectangular wave signals in amplitude limiters 4A-4G. Then, by the sub band rectangular waves of 40-680Hz frequency divided by frequency dividers 6A-6G, carrier waves are amplitude-modulated in modulators 7A-7G and outputted. Thus, output is performed as frequency divided sub band signals whose amplitude is the same as sub band signals and frequency is 1/5. Then, the signal components of respective frequency divided sub bands are extracted, synthesized and outputted by the band-pass filters 8A-8G. Thus, the speech signals are compressed to the narrow frequency band of 40-680Hz and the spectral peak of the feature quantity is faithfully reproduced.

Title: Combustion control device of internal combustion engine
Inventor: KAWAI TAKASHI
IPC: F02D41/14
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To provide a combustion control device of internal combustion engine of cylinder injection spark ignition type allowing easy diagnosis of a failure in the fuel system and capable of minimizing the prohibition of lean combustion for failure diagnosis. SOLUTION: Lean combustion is prohibited when such a diagnosis is passed that normal condition of the fuel system is not distinct according to a preliminary diagnosis (S350) under the warmup process. Accordingly the air-fuel ratio feedback control in the stoichiometric condition is established even if the operating condition is stabilized sufficiently, and an accurate diagnosis by a failure diagnosis (S390) can be achieved easily. Furthermore, if the preliminary diagnosis (S350) is that the fuel system is normal, the lean combustion remains unprohibited (S360). The operation, therefore, can manage without forced stoichiometric combustion in the operating condition in which lean combustion is possible even though the fuel system remains normal. Thus there is no risk that the fuel consumption is deteriorated too much.
